Description
Technical field
The present invention relates to a kind of refrigerating chamber is used evaporimeter with evaporimeter and refrigerating chamber refrigerator and control method of refrigerator that have.
Background technology
Refrigerator is provided with refrigerating chamber and refrigerating chamber usually.Recently on the refrigerator of development the refrigerator that is provided with special evaporator in each cool room is respectively arranged.Figure 13 has shown the kind of refrigeration cycle of these evaporimeters.
The downstream that the kind of refrigeration cycle 100 of Figure 13 ties up to compressor 102 is connected with condenser 103, branch in the downstream of condenser 103 two: one branched pipes be connected with refrigerating chamber with transfer valve (hereinafter referred to as the R valve) 104, refrigerating chamber with capillary (hereinafter referred to as the R capillary) 106 and refrigerating chamber with evaporimeter (below, be called the R evaporimeter) 108; Another branched pipe be connected with refrigerating chamber with transfer valve (hereinafter referred to as the F valve) 110, refrigerating chamber with capillary (hereinafter referred to as the F capillary) 112, refrigerating chamber with evaporimeter (below, be called the F evaporimeter) 114 and check-valves 116.In addition, the stream from check-valves 116 and R evaporimeter 108 is circulated to aforesaid compressor 102.
Again, R evaporimeter 108 is provided with the R fan 118 that is used for the air of cooling is delivered to refrigerating chamber, also is provided with F fan 120 on F evaporimeter 114.
Below, with reference to Figure 14, do an explanation with regard to the control method in the past in the above-mentioned kind of refrigeration cycle 100.
The described controlling party genealogy of law is alternatively carried out the refrigeration running (below, be called the R pattern) of refrigerated compartment and is cooled off the cooling control method of the freezing running of refrigerating chamber (below, be called the F pattern).Particularly, when refrigerating chamber reaches institute's fixed temperature, close R valve 104, open F valve 110, cold-producing medium is flowed in the F evaporimeter 114, carry out the running of F pattern.Again, in the running of F pattern, when refrigerating chamber reach during fixed temperature, close F valve 110, open R valve 104, cold-producing medium is flowed in the R evaporimeter 108, carry out the running of R pattern.
Yet R evaporimeter 108 is different with evaporating temperature in the F evaporimeter 114, and the heat of evaporation enthalpy is also different.For this reason, as with the cooling heat of R evaporimeter 108 and 114 palpuses of F evaporimeter simultaneously as 40W, then by the difference of evaporation enthalpy heat, make that the refrigerant flow of R evaporimeter 108 is two times of F evaporimeter 114.That is, when evaporating temperature rises to high temperature from low temperature, because the difference of the volumetric ratio of the soakage of compressor 102 makes essential refrigerant flow increase.
Because the circulating mass of refrigerant of above-mentioned R evaporimeter 108 and F evaporimeter 114 is different, make at cooling operation when the F pattern is converted to the R pattern, the slow of cold-producing medium operation taken place.Its reason is: at first, in the F operation mode, amount when cold-producing medium flows with a unit quantity when switching to the R mode operation, needs 2 times discharge: secondly, in the F operation mode, the compression ratio of compressor 102 is bigger, but when being converted to the R pattern, its compression ratio reduces, because the difference of this compression ratio makes cold-producing medium be difficult to flow to R evaporimeter 108.
And, be cause with the slow of above-mentioned cold-producing medium operation, as shown in figure 13, the state of cooling only takes place at the intake section of R evaporimeter 108, its problem is: be reduced to below the necessary temp as near the temperature will not exporting, then can not obtain sufficient cooling effect.This has influence on cooling capacity.
Again, the cold-producing medium that is stranded in F evaporimeter 114 can't flow to compressor 102 1 sides also because of under the R operation mode that is in increased pressure, and the cold-producing medium circular flow reduces, and can't regulate.For this reason, when running, the circulating mass of refrigerant in the kind of refrigeration cycle 100 promptly changes.And this becomes the reason that cold-producing medium moves slow generation once more.
Because circulating mass of refrigerant can't be correctly controlled in the existence of the problems referred to above, also can't correctly control cooling capacity.

The specific embodiment
The 1st embodiment
Below, with reference to Fig. 1-Fig. 3, describe with regard to the 1st embodiment of the present invention.
Figure 1 shows that the timing controlled flow chart of the state of a control in the present embodiment refrigerator 1.Fig. 2 is the longitudinal sectional view of refrigerator 1.Fig. 3 is the kind of refrigeration cycle 10 of refrigerator 1.
At first, according to Fig. 2, the structure of refrigerator 1 is described.
In the Machine Room 6 at refrigerating chamber 5 back sides, be provided with compressor 12.Be provided with F evaporimeter 24 and F fan 30 at ice-making compartment 4 back sides again.Have again, be provided with R evaporimeter 18 and R fan 28 at the back side of vegetable compartment 3.Have, the condenser that nearby being provided with of compressor 6 is used for cooling compressor 12 and condenser 13 is with fan (below, be called the C fan) 32 again.
Again, with FR evaporimeter 24 cooling ice-making compartment 4 and refrigerating chambers 5, with R evaporimeter 18 refrigerated compartment 2 and vegetable compartment 3.
Secondly, according to Fig. 3, do an explanation with regard to the structure of the GM Refrigerator Working 10 of present embodiment.
Be connected with condenser 13 in the downstream of compressor 12, branch into two in the downstream of condenser 13.On a side runner, be connected with the R valve 14 that constitutes by two way selected valve, be connected with R capillary 16, R evaporimeter 18 under it.Again, on the opposite side runner, be connected with the F valve 20 that constitutes by two way selected valve, be connected with F capillary 22, F evaporimeter 24 under it.Be connected with check-valves 26 in the downstream of F evaporimeter 24.And, be combined into one from the runner of check-valves 26 and from the runner of R evaporimeter 18, be circulated to compressor 12.
Below, with reference to timing flow chart shown in Figure 1, do an explanation with regard to the duty of refrigerator 1.
1.F pattern
In the F pattern of cooling ice-making compartment 4 and refrigerating chamber 5, close R valve 14, open F valve 20.Again, disconnect R fan 28, energising F fan makes C fan 32 turn round with ordinary rotational speed.
Then, cold-producing medium does not flow to R evaporimeter 18, but flows to F evaporimeter 24, cooling F evaporimeter 24, and the air of cooling is sent to ice-making compartment 4 and refrigerating chamber 5 by F fan 30.At this moment, the evaporating temperature of F evaporimeter 24 is about-25 ℃.
2. from the transition period of F pattern to the conversion of R pattern
Temperature is reduced to institute's fixed temperature in the refrigerator of ice-making compartment 4 and refrigerating chamber 5, otherwise temperature is increased to institute's fixed temperature in the refrigerator of refrigerating chamber 2 and vegetable compartment 3, at this moment, must carry out from the switching of F pattern to the R pattern.At this moment, carry out switch transition by the following stage.
As the 1st stage, not only close R valve 14, also close F valve 20.Again, C fan 32 runs up.Under this state, the cold-producing medium that is stranded in the F evaporimeter 24 is drawn, reclaimed to continuous running compressor 12, and the cold-producing medium that reclaims is delivered to condenser 13.In condenser 13, because C fan 32 is running up, therefore, condensation is carried out, and the liquefaction of cold-producing medium obtains promoting that the cold-producing medium of liquefaction is stranded in condenser 13.
The running in above-mentioned the 1st stage is called the refrigerant-recovery running.And this refrigerant-recovery running is only carried out to setting-up time t1 (for example 2 minutes) after stopping from the F mode operation.
As the 2nd stage, when the refrigerant-recovery running stops, close F valve 20, directly open R valve 14, make the refrigerant flow direction R evaporimeter 18 of condenser 13 liquefaction.
So, the cold-producing medium that is stranded in condenser 13 liquefaction flows to R evaporimeter 18 easily, and it is identical to make that inlet temperature and the outlet temperature of R evaporimeter 18 are close to, and it is slow to eliminate the cold-producing medium operation.
The 2nd embodiment
Below, with reference to Fig. 4, do an explanation with regard to the 2nd embodiment.
The difference of present embodiment and the 1st embodiment is: by the outlet temperature of F evaporimeter 24 to judging to the termination time of the refrigerant-recovery running of R mode transition from the F pattern.
Like this, the cold-producing medium that is stranded in F evaporimeter 24 inside evaporates because of the temperature in the refrigerator.Again, owing to the pressure of taking out of compressor 12, F evaporimeter 24 inside become vacuum state.Thus, make the temperature of F evaporimeter 24 low gradually as shown in Figure 4.
Yet owing to do not have heat exchange without cold-producing medium, therefore, temperature begins to rise once again in the refrigerator.When the outlet temperature of the F evaporimeter 24 that this begins to raise was higher than 2 ℃ of design temperature (for example ,-25 ℃) or 3 ℃, the recovery running of cold-producing medium stopped, and R valve 14 is opened.
So, can judge the termination timing of refrigerant-recovery running reliably.
The 3rd embodiment
Below, with reference to Fig. 5, do an explanation with regard to the 3rd embodiment.
Difference is: in the 1st embodiment, when the refrigerant-recovery running stops, switches to the R mode operation, but in the present embodiment, directly do not make 28 revolutions of R fan this moment, but, even it stops at the beginning.
That is, after the refrigerant-recovery running switches to the R pattern, R fan 28 at the beginning promptly shuts down.And, till the outlet temperature that the halted state of this R fan 28 is continued to R evaporimeter 18 reduces.Described R fan 28 is only stopped in setting-up time t2 again.
Yun Zhuan reason is as mentioned above: if refrigerating chamber 2 and vegetable compartment 3 (temperature) in the F pattern increase, under its state, flow of refrigerant is rotated R fan 28, then promptly can be R evaporimeter 18 in vaporized refrigerant liquid, form and gasify.Thus, the pressure in R evaporimeter 18 pipe arrangements is risen, and the gas pressure loss also increase, so, the phenomenon that cold-producing medium is difficult to flow produced.For this reason, restrain above-mentioned gasification, cold-producing medium is finally flowed to the exit of R evaporimeter 18, can reduce the temperature of R evaporimeter 18 equably, guarantee the cooling capacity that it is higher.
The 4th embodiment
Below, with reference to Fig. 6, do an explanation with regard to the 4th embodiment.
Present embodiment is different with 1-the 3rd embodiment.State of a control when in the present embodiment, having represented to stop compressor 12 by the F pattern.Again, the structure of refrigerator 1 and kind of refrigeration cycle 10 is as the 1st embodiment.
When the F mode operation stops, not only close R valve 14, and also close 2F valve 20.In addition, R fan 28 is in off-state, and F fan 30 keeps on-state.Again, C fan 32 is with common rotating speed revolution.Under this state, compressor 12 so the liquid refrigerant that is stranded in the F evaporimeter 24 is drawn recovery, and is delivered to condenser 13 in running.Spue to the revolution of the cold-producing medium of condenser 13, carry out liquefying after the condensation, under becoming the state of liquid refrigerant, be stranded in the condenser 13 because of C fan 32.Below, this operating condition is called stops to prepare operating condition.
Above-mentionedly stop to prepare operating condition from the terminal hour of F pattern, through behind the fixed time t3, compressor 12 is stopped.
By above-mentioned compressor 12 stop to prepare running, when the running that returns back to compressor 12 next time, cold-producing medium flows to evaporimeter easily, thus, can eliminate the slow of cold-producing medium.Again, in the running of compressor 12 stops, interrupting condensers 13 and R evaporimeter 18, F evaporimeter 24, make the hot gas of condenser 13 not flow into two evaporimeter inside, the temperature of evaporimeter can not raise by F valve 20 and R valve 14.That is, the temperature in the refrigerator 1 does not raise, and its answer is also fast.
Again, in the above-described embodiments, the F mode operation at the end carries out above-mentionedly stopping to prepare to turn round, but in the R mode operation, also can carry out same stopping and preparing running.
The 5th embodiment
Below, with reference to Fig. 7, do an explanation with regard to the 5th embodiment.
The difference of present embodiment and the 2nd embodiment is: be not by the time of setting, but judge that by the amount of drive current of compressor 12 termination stops the timing of preparing to turn round.That is, in the F pattern, compressor 12 turns round with the drive current I of about 0.5A (50W), but prepares in the operation process stopping, and can produce the poor of pressure and suction pressure that spue, and adds load on the compressor 12, and the input of drive current I is risen.
Yet, reducing as the refrigerant amount that sucks, the load of compressor 12 reduces, and the input value of drive current I also descends.Drop-out value when detecting described decline can judge that this moment, cold-producing medium reclaimed, and compressor 12 is stopped.
Thus, can in refrigerant-recovery, make definitely to stop to prepare the running termination.
The 6th embodiment
In the 1st to the 5th embodiment, R valve 14 and F valve 20 are to constitute with two way selected valve respectively, but also 2 valve integratedization can be constituted a three-way diverter valve, replace described two way selected valve structure.
The inlet of described three-way diverter valve is one, and outlet has two, and following three kinds of states can be arranged.
The 1st state is, the 1st outlet (outlet of leading to R evaporimeter 18) is opened, and the 2nd outlet (outlet of leading to F evaporimeter 20) is closed.
The 2nd state is, the 1st outlet (outlet of leading to R evaporimeter 18) is closed, and the 2nd outlet (outlet of leading to F evaporimeter 20) is opened.
The 3rd state is, the 1st outlet (outlet of leading to R evaporimeter 18) is closed, and the 2nd outlet (outlet of leading to F evaporimeter 20) is closed.
The 7th embodiment
Below, with reference to Fig. 8-Figure 11, do an explanation with regard to the 7th embodiment.
Fig. 8 represents the structure of the kind of refrigeration cycle 10 of present embodiment, and the difference of itself and the 1st embodiment is, three-way diverter valve 34 is set replaces R valve 14 and F valves 20.Between F evaporimeter 24 and check-valves 26, be provided with storage heater 36 again.Again, three-way diverter valve 34 has three kinds of full cut-off types under the possibility state: make the occasion of refrigerant flow direction R evaporimeter 18, make the occasion of refrigerant flow direction F evaporimeter 24 and make cold-producing medium not flow to the occasion of R evaporimeter 18 and F evaporimeter 20 simultaneously.
(1) control method in the past
At first, just control method is in the past done an explanation.
The situation of the desirable variations in temperature of the R evaporimeter 18 in carrying out the mutual cooling operation process of F pattern and R pattern alternately and the pressure state of F evaporimeter 24 and each evaporimeter sees Fig. 9 for details.
Usually, in the R pattern, when the pressure and temperature of R evaporimeter 18 is about 0.2Mpa-10 ℃.On the other hand, in the F pattern, when the pressure and temperature of F evaporimeter 24 is about 0.1Mpa-26 ℃.
That is, as shown in Figure 9, in the R pattern, the pressure in the evaporimeter is the height of R evaporimeter 18 than F evaporimeter 24, by this pressure differential, check-valves 26 cuts out, and the refrigerant of low temperature storage is stayed in F evaporimeter 24.And, in case switch to the F pattern, promptly can cool off with low-temperature refrigerant from this state, under the F pattern, can effectively cool off, and can not produce the slow of cold-producing medium.
Secondly, in the F pattern, when the pressure and temperature of F evaporimeter 24 is about 0.1Mpa-26 ℃, and the temperature of R evaporimeter 18 is 0 ℃-2 ℃, its pressure is identical with F evaporimeter 24, is 0.1Mpa.
Therefore, in the F pattern, because the pressure of R evaporimeter 18 is in below the saturation pressure, cold-producing medium evaporates, and layer is a drying regime.Three-way diverter valve 34 from then on state switches, and when transitting to the R pattern, produces the slow of cold-producing medium, and cold-producing medium must several minutes in outlet one side that arrives R evaporimeter 18.One of the variations in temperature of this moment and operating condition is illustrated in Figure 10.
As shown in figure 10, produce the slow of cold-producing medium operation on the R evaporimeter 18, under this state, R evaporimeter 10 can not generate effectively.Again, as because some reason refluxes from check-valves 26, the state of lack of refrigerant takes place on R evaporimeter 18 then.
For avoiding described state, the rotating speed of control compressor 12 makes it corresponding to above-mentioned state, then because of numerous and diverse variation takes place rotating speed, produces abnormal noise or noise, and the unfailing performance of compressor 12 is low.
Again, under normal condition, cold-producing medium is stranded in the lower evaporimeter of temperature one side, when the indoor temperature of refrigerating chamber 2 and refrigerating chamber 5 was near outside air temperature after feeding power supply, switching three-way reversal valve 34 cooled off alternately, in this process, sometimes, cold-producing medium is stranded in R evaporimeter 18 inside more, can think, also lack of refrigerant can take place in the F pattern.
So, implement the control method of present embodiment as described below.
(2) this control method
Below, with reference to Figure 11, this control method is described.
Figure 11 represents from feeding power supply to the process of normal condition, the temperature of R evaporimeter 18 and F evaporimeter 24.
As above illustrated, cold-producing medium is stranded in the low evaporimeter of temperature one side, but during the higher load condition after feeding power supply, and there is the mutual situation of R evaporimeter 18 and F evaporimeter 24 in the evaporimeter that becomes low temperature one side.
Therefore, before switching to the R pattern, and before switching to the F pattern, carry out the refrigerant-recovery running from the R pattern from the F pattern.The recovery running of above-mentioned cold-producing medium is as illustrated ground in the 1st embodiment, close three-way diverter valve 34, cold-producing medium is flowed in R evaporimeter 18 and the F evaporimeter 24 simultaneously, running compressor 12, cold-producing medium is all sent in the condenser 13, revolution C fan 32 reclaims the cold-producing medium that is necessary in condenser 13 1 sides in condenser 13.
Particularly, promptly carry out R mode operation, refrigerant-recovery running, F mode operation, refrigerant-recovery running and R mode operation repeatedly, cool off.
Thus, because can make necessary cold-producing medium shift to condenser 13 1 sides before the switching of each pattern, so, after switching, it is slow can not produce the cold-producing medium operation on each evaporimeter, can give full play to performance of evaporator, high efficiency cooling, shortens cool time.
The 8th embodiment
Below, with reference to Figure 12, do an explanation with regard to the 8th embodiment.Present embodiment is the variation example of the control method among the 7th embodiment.
(1) the 1st control method
Below, the 1st control method is described
Because it is effective that refrigerant-recovery operates under the R pattern, so, describe with the R operation mode.
In Figure 12, suppose that in the cooling of R pattern (1) inlet temperature of R evaporimeter 18 and the temperature difference of outlet temperature increase, the state of lack of refrigerant takes place.Particularly, respectively at the inlet side of R evaporimeter 18 and export a side Temperature Detector is set, according to temperature that this Temperature Detector detected if temperature difference can be judged the state that is in lack of refrigerant as described above.In addition, proceed the running of compressor 12 and C fan 32, three-way diverter valve 34 is made full-shut position, transit to refrigerant-recovery running (2).
Continue to carry out described refrigerant-recovery running (2), for example, after 1 minute, transit to the R pattern (1) before the refrigerant-recovery running again.
So, in R pattern (1), the slowly leakage of cold-producing medium takes place from check-valves 26, cold-producing medium flow to F evaporimeter 24 from R evaporimeter 18, though lack of refrigerant, also can be by the recovery of cold-producing medium, bring into play the performance of R evaporimeter 18 once again and cool off, simultaneously, keep the balance of refrigerant amount.
Again, the judgement of above-mentioned lack of refrigerant system carries out according to the inlet temperature of evaporimeter and outlet temperature, but, when also can the air themperature in being blown into refrigerator rising, judge lack of refrigerant.
(2) the 2nd control methods
Below, the 2nd control method is described.
When cutting apart mutual cooling running or switching alternately by the state of temperature in the refrigerator, in generating the slow R pattern of cold-producing medium easily, as refrigerant-recovery running (1) (3) (4), before being converted to the R pattern, carry out the refrigerant-recovery running from the F pattern.
Promptly, be communicated at three-way diverter valve 34 under the state (F pattern) of F evaporimeter 24 1 sides,, as receive the instruction of switching the R pattern by the temperature in regular hour or the refrigerator, when the running of compressor 12 and C fan 32 continued, three-way diverter valve 34 became full closing state.So F evaporimeter 24 inside or the storage heater 36 inner majority system cryogens that are detained are shifted to the liquefaction of condenser 13 1 sides.
Carry out aforesaid refrigerant-recovery functioning example as 1 minute after, switch the R pattern, make three-way diverter valve 34 be communicated to R evaporimeter 18 1 sides.
By described control, in refrigerator, under the stable state of temperature near design temperature, in generating the slow R pattern of cold-producing medium easily, can give full play to the performance of R evaporimeter 18, simultaneously, cool off efficiently, obtain high refrigerating capacity.
(3) the 3rd control methods
The yield of the cold-producing medium that is reclaimed owing to turning round by refrigerant-recovery depends on the rotating speed of compressor 12, so, be preferably, to carry out the recovery of cold-producing medium proportional duration of runs with the rotating speed of compressor 12.
In Figure 12, the rotating speed of F pattern (2) is 50Hz, is converted to R pattern (2) in cooling.At this moment, the rotating speed of compressor 12 continues the rotating speed of the 50Hz that set before its conversion.The recovery time t3 of this moment is 1 minute.
Secondly, the rotating speed of F pattern (3) is 30Hz, is in the cooling, as above-mentioned, when being converted to the R pattern, continues the rotating speed of 30Hz.Be converted to refrigerant-recovery running (4).
The recovery time t4 of this moment is set at 3 minutes, that is, and and 1 minute of the t3 when carrying out refrigerant-recovery with 50Hz.
That is, the refrigerant-recovery time set with the rotating speed of compressor 12 when low by this, can reclaim cold-producing medium in right amount the refrigerant-recovery duration of runs when higher greater than rotating speed.
(4) the 4th control methods
In the refrigerant-recovery running, except the rotating speed of as above illustrated compressor 12, the yield of the cold-producing medium of recovery also can be dependent on refrigerator 1 residing outside air temperature.
Therefore, set the duration of runs of refrigerant-recovery running, make it,, when outside air temperature is high, shorten the duration of runs when the low time delay long running time of outside air temperature corresponding to outside air temperature.
(5) the 5th control methods
In the refrigerant-recovery running, the evaporimeter of recovery cold-producing medium one side or storage heater 36 reduce temperature because of the evaporation of cold-producing medium.At this moment, revolution makes circulating cold air corresponding to the R fan 28 or the F fan 30 of this evaporimeter, also can help the temperature in the refrigerator to keep constant temperature.
That is, in the refrigerant-recovery running (4) of Figure 12,, the temperature of F evaporimeter 24 is descended when the temperature decline of R evaporimeter 18.At this moment, by rotating F fan 30, can in the refrigerant-recovery running, cool off refrigerating chamber 5.
The F fan dwell time of this moment is set by the following method.
Be about 1-2 minute the duration of runs of F fan 30 or R fan 28, and the described duration of runs, the long fan input power that will cause increased temperature rising in the refrigerator that reaches thereupon.
For this reason, when the temperature that detects F evaporimeter 24 rises, when rising to more than one 20 ℃, promptly stop IE F fan 30 as the temperature of this evaporimeter.
